1' Claim. 1

-"My invention relates to storm windows r' Sl1p'- plementary windows of thecasement type, and is here shown as comprisinga. master frame that includes glazed,1hinged storm sash nesting in the frame, thecframebeing permanently attached to theexterior faces of varioust'ypes or designs of standard or' 'special' out-swinging casement windows,"whereby to secure the advantages of a doubleglazed window.

' Gne object of my invention to provide a storm sash that need notibe removed for ventilation, cleaning or the" installation of interior screens, thearrangement' having the further advantage of being especially. suitable for aire'conditionedrbuildings, because of the dead airspace.

My'improved structure has further advantages. such as minimizing sweating and the leakage of air and dirt, and the use of a semi-liquid sealing compound between" my master frame and the casement windows to which theframe is applied, prevents rust or corrosion between the metal-tometal surfaces, and serves as a water-proof seal.

While the invention is. described more particuiarly'as applied to an already-installed casement window, obviously my storm window can be applied to a casement window frame at the factory and the complete combination shipped and installed as a unit.

As shown in the accompanyin drawings, Figure 1 is an outer face view of my storm window; Fig. 2 is a perspective view thereof, on a reduced scale, showing the storm windows in open position, at the outer face of the casement window structure; Fig. 3 is a view taken on the line III--III of Fig. 2; Figs. 4, 5, 6 and '7 are views taken on the lines IVIV, V-V, VI-VI and VIIVII respectively of Fig. 1, on enlarged scales; Fig. 8 shows a modification wherein the transom of the structure of Figs. 4 and is omitted; Fig. 9 is an enlarged face view of an upper portion of the structure of Fig. 1, below the transom of Figs. 1 and 5; Fig. 10 is a view taken on the line X--X of Fig. 9; Fig. 11 is a view on an enlarged scale of the lower righthand corner of Fig. 1; Fig. 12 is a view taken on the line XII-XII of Fig. 11; Fig. 13 is a view taken on the line XIII--XIII of Fig. 11; Fig. 14 is a side view of one of the reinforcing angles of Figs. 9 and 10; Fig. 15 is an edge view thereof; Fig. 16 is a face view of a standard casement window before installation of my storm window thereon; Fig. 17 is a face view of a standard hinged casement sash frame employed in conjunction with the frame of Fig. 16 and Fig. 18 is an enlarged plan view of one of the hinges of Figs. 2 and 11.

The sash frames. ofFigs'. 16 and 1'7 maytsuita bly be of'steel or aluminum and when assembled, will fit a window op'eningj'of standardformJTf'he large frame l9 comprises stile members'VZOi; a lintel member 2i; azbottom bar 22,, a mullion b'a'r' 2'3an'da cross bar 24; sash bars125rare'connected across the stile!!! and the mull'ionbar 23., and panes 26 are. set into. thetfra'm'e. thus formed, these being the inner panes of thawindow." Similarly, the auxiliary sash frameilfii'of Fig: l'lihas'stile' members 29 and. cross bars130,

3|; 32 andi33 in which are mounted. glass panes 34. This auxiliary frame 28 is hinged at: 35'" to one of. the stilesZll, so that it can be. swun out:-

'wardly from the position shown Fig. 7 to. the

position shown in Figs. 2,, 3 and 11.

. A transom window comprises..a,framel 31 .(Fig. 4') that is rigidlyconnected. to: the l'intellb'arlll andfithe stiles 25., as. by. screws. 38... :sas'h frame. 3!!- has. as'wing'ing. sash. 6.9 hingedly con-' nectedsthereto at. 4i...and' carriespanes ofglass 42. Transom. panes 43' are mounted. in the-mam bersLZll,,.2.l,' 23 and Z4. ofFig. 16.

Springy flashing strips 44 are provided for the upper and lower edges of the transom, and flashin strips 45 and 46 extend downwardly along the vertical edges of the transom as shown in Fig. 6, the strip 45 extending clear to the bottom of the window while the strip 46 terminates at the lower edge of the transom. Below the strip 46, a sealing angle 41 is provided as shown in Figs. 7 and 1.

A swinging storm sash 48 (Figs. 2, 5 and '7) is hingedly connected at 49 to a storm window frame 50 that is secured by screws 50a to the left-hand stile 28 of the sash frame l9. An outer window pane 5| is mounted in this frame 48 between a rubber strip 52 and a sprin spline 53, as shown in Fig. 7 and on a larger "scale with the pane of Fig. 13. The, sash 48 will swing open on the frame50 as indicated in Figs. 2 and 3.

The auxiliary sash frame 28 has a sash frame 54 connected thereto by screws 55, and these members are hingedly connected at 35 to the right hand rigid frame stile 20 in accordance with standard practice, as shown more clearly in Figs. 11, 13 and 18. A swinging storm sash 56 is hingedly connected at 51 to the frame 54.

Flashing strips 58 are provided for the lower edge of the window, to bear against the sill, and at the upper edge of the frame of Fig. 8.

stiffening angles 56 and 68 are provided in the corners of the frame structure, the angle 59 having drive fit with the frame members 31 and the angle 60 having drive fit with the sash members 39, as shown more clearly in Figs. 9 and 10.

When it is desired to open the windows for ventilation or for cleaning, a crank 63 is turned to swing the frame 28 outwardly, in a manner well known in the art, thus opening the-window frame 28. Also, the swinging sash frame 56 can then be swung on its hinges 51, to bring the the sash 56 will then be accessible for cleaning.-

Also, the cleaner can reach to the outer face of the glass 26 and to the vinnerface of the glass 5l ,'..to clean them. Of course, when the glass 'BI is closed, the outer face thereof is clearly accessible by one reaching outwardly through the opening acrosswhich the frame 28 is hung.

Spring clips 66 are provided at various points throughout the structure, as shown more clearly on Figs. 1 and '7, to hold the swinging panels snugly against their frame memberswhen the windows are closed. Also, non-hardenable adhesive or mastic is provided, at various points where there is ordinarily'fixed metal-to-metal engagement between the parts, as shown at E? in various of the figures,.such as in Figs. 18, 4 and 6. Suitable latching devices will be provided as indicated at 68.

It will, of course, be understood that the sash frame members of Figs. 16 and 17 may be of steel,

aluminum, wood or other suitable materials.

Where aluminum is employed in the structure, as

for example in the case of the frames 28, 3! and 54, the interposition of the mastic 67 between the aluminum and the steel members protects the aluminum against corrosion as well as preventing 4 air leaks and condensation of moisture. It will also be seen that there is but limited direct path for conduction of cold or heat through the metal members, as will be apparent in viewing Figs. 7

and 18 for example, wherein although inner and outer metal members have direct contact except for the mastic, there are staggered air spaces.

In Fig. 8, a slightly different form of window structure is shown. The principal difference between this and the other structures is that the transom is omitted, that portion of the frame l9 above the bar 2d being cut away. In this arrangement, the auxiliary sash frame 28 and its swinging-storm sash will be mounted in the same manner as in theother figures and the frame 56 for the swinging sash 48 similarly mounted.

I claim as my invention:

A window structure comprisingra main casement frame installed alongside a fixed closure means of extended area, anauxiliary sash frame hinged at one edge to vthe main frame, by a pair of hinge leaves which extend perpendicularly from the planes of the frames and are pivotally connected at their outer ends, andare of such length that when the auxiliary sash frame is swung from a normal position of parallelism with respect to the main frame, the adjacent hinged edges of the frames become separated fora distance sufficient to permit an operator to extend his arm to the exterior of the window, and a storm window sash hingedly connected to the auxiliary sash frame at the free edge of the auxiliary sash frame and being movable thereon, to form a double-paned window structure.
